CARPET CLEANING AND DISINFECTING MACHINE.

Patented March' 27, 190e,

Application filed November 2, 1903. Serial No. 179,455.

I all wrtom it mag concern.-

Be it known that I, EUGENE A. THOMAS, a

citizen of the United S'tatesxresidirig at Chi-- cago, in the county ofCook and State of Illi no s, have invented certain new and usefulImprovements in Carpet Cleaning and Disin- "fecting Machines, of whichthe following is a specification.

This invention relates to improvements in machines for cleaning anddisinfecting textile fabrics, carpets, rugs, and the like by coinpressedair or steam impregnated with adisinfectant.

Among the objects of the invention are to provide a sim le, strong, anddurable apparatus of this 0 aracter which will be efficient in itsoperation and by the use of which a single attendant will be able toreadily handle, clean, disinfect, and renovate carpets, rugs, and othertextile fabricsof almost any length. The width of the apparatus will ofcourse art as a limitation upon the width of the carpets and rugs whichmay be cleaned therein; but

it is entirely practicable to construct a ma chine which will take anywidth of carpet.

The invention consists in the matters hereinafter set forth andparticularly pointed out in the claims.

In general terms a carpet-cleaning apparatus embodying my invention inits pre-. ferred form comprises in its construction a carrierconsisting, preferably, of link belts adjusted to sprocket-wheelssecured to shafts revolubly mounted in suitable bearings'in themachine-frame and provided at intervals with suitable transverse slatsupon which the carpet or other article is supported. This carrier 1ssupported in a substantially horizontal position and is of considerablelengthsay, for example, twenty-five feet. The cleaning instrumentalitiescomprise, primarily, one or more air-jets supported above the carrier,adapted to )roject a jet or jets of air downwardly upon t e carpet onthe carrier at any inclination desired, air being sup plied to said jetsthrough connection with a source of supply of air under pressure.Preferably, also, the cleanin instrumentalities comprise, in additiontot 1e above jet or jets, a fjet or jets which extend transverselythere- 0 directly beneath the upper lap of the car rier and adapted toproject a jetor jets of air upwardly against the under surface of acarpet or other article supported on said carrier.

in advance or said jets, adapted to run in 'contact with the u persurface of a carpet or other article an ,mopposite direction to themovement of the carpet, which brush operates to loosen and raise thepile ornap of the article, so as to allow the air-jet to penetrate thesame more'easily and thoroughly: The carrier andcleaninginstrumentalit-ies are illclosed within a suitable casing,preferably made of sheet metal, which is designed to confine the dustand dirt expelled from the carpet or other article being-cleaned. Thebot.

tom of'the casing is trough-shaped and declines toward anoutlet-opening, and the interior of the casing beneath the carrier is'designed to he s r'ayed with water from a suitable system 0 pipesprovided for the purpose, whercbv the dust and dirt expelled from thecarpetb Y the jets of compressed air will be caught or preclpit-ated bythe spray and carried. off by the current of water through the outletopening, which may be connected with the sewer or other drainage system.This may be effected by a pipe of diameter sufficient for the purpose,with perforations of a size and at distances as may be desired orrequired, extended'across the up er end or head and alon the sides oftie casing slightly raised above the bottom thereof and connected at thefront or u some. water-supply with sufficient pressure so that the waterdischarged through the erforations in form of jets or spray will toroughly wash out all dust and dirt that mayor shall fall to thetrough-shaped bottom of the casing and carry the same out through a apipe at the lower end of the casing and into the pipe leading from thefan through which the dust is expelled, precipitating the dust andcarrying it in a muddy stream, so ion as there is any dust, into thesewer or at or drainage system.

In the operation of the machine it is designed that one or more of thecarrier-.

supporting shafts will be positivel driven through connection withanysuitab e source of power and in such manner that the direction ofrotation of said shaft can be reversed as desired. A section of thecasing-wall inclosing the front end of the carrier is made removable,comprising, preferably, a hinged sectionor door which may be, opened topermit access to the carrier for the purpose of attaching the carpet orother article thereto and through which said carpet m rug is drawn intothe casing and removed there;

Mini r er end with machine.

from. Power being applied to the carriershat't to impart movementthereto in the m per'direction, the carpetor other article w be drawninto the machine upon the up ne lap of the carrier and willbe e. osed totheaction of the brush and blast rom the arnjets. The air-jets supportedabove the c rrier are preferably directed rearwardly at an acute an le,so that the blast will natuany reboun from the surface of the carpet,thus tending to blow the dust and dirt upwardly-out of the carpet ratherthan to force it down into and through the car et, as would be the casewere the jets directedhit ri ht angles to the surface of said carpet. Te can ier movement is continued until the entire ength of the carpet hasbeen subjected to the action of the brush and air-jets, the forward endof the carpet when of considerable len th passing around the end of saidcarrier an moving rearwardly with its lower lap until the entire lengththereof has been resented to the action of the brushes and ets. Thedirection of movement is then reversed and the carpet drawn back pastthe air-jets and removed. A sin is complete exposure of the car et tothe action of the air-jets while moving oth forward and backward pastthem should suffice to thoroughly cleanse and renovate the' same. All ofwhich will be more fully understoodfrom the following detaileddescription, illustrated in the accompanying drawings, in which-*Figures 1, 1, and l together form a general view, partly in sideelevation and artly in section, of a carpet-cleaning machine of myinvention. Figs. 2, 2", and 2 together form a top plan view of a machineof my invention, the casing'being removed from one side thereof to showthe operative parts of the Fig. 3-is a transverse vertical sectionalview on the line 3 3 of Fig. 2.

Fig. 12 is a detailsectional view of the ivotal connection between the supplementallast-pipes 28 and 2 l The frame of the machine consists of longitudinalframe members 1,which extend continuously the entire length of themachine at each side thereof, transverse frame 'tudinal of said machine.

members 2, which connect the longitudinal frame members 1, and legs 3-,upon which the longitudinal frame members 1 are su ported.

During the operation of the maciime the carpet or other article to becleaned, disinfected, and renovated is supported upon a carrier(indicated as a whole by A) mounted upon the Inachine-frame in suchmanner as to be freely movable in both directions longi- As shown, saidcarrier consists of transverse slats 4, secured at intervals to linkbelts 6, adjusted to sprocketwheels 7, secured to shafts 8, revolublymounted in suitable bearings on the longitudinal frame members l,sa1dshafts 8 being provided at such intervals that the upper ap of thecarrier will be su ported substantially level. To prevent t he endshafts 8 from springing under the strain to which they are subjected,which would allow the carrier to sag, said shafts are provided with oneor more bearin s in suitable rigid subports intermediate t e endbearings thereof. As shown, the intermediate bearings for said endshafts are formed in bars 9, which are supported in fixed longitudinaladjustment by means of braces or truss-rods 10, the ends of which aresecured to the longitudinal frame members 1 and against which the innerends of said bars 9 bear.

To provide for ti 'htening the carrier A, either in adjusting the samein the first instance or to take up wear or stretch thereof, thebearings of one or both of the end shafts S are adjustable in thedirection of the length of said carrier. As shown, the rear shaft onlyis thus adjustable, the outside or end bearings and tlie intermediatebearings being adjustable independently of each other. To effect desiredadjustment of the outside or end bearings of said shaft, said bearingsare, as shown in Figs. 2 and 11, formed in blocks 11, slidabl Y mountedon base-plates 12, secured to the longitudinal frame members 1, and areadapted to be forced outwardly by thrust-screws 13, threaded throu hlugs 14 on said base-plates. To provide or desired adjustment of theintermediate bearing or bearin s of said shaft, the ends of the trussrod or race 10 instead of being secured directly to the lon itudinalframe members 1 are secured to bl ocks 15, slidably mounted onbase-plates 16, secured to said longitudinal frame members 1, andadjustment of said blocks 15 is effected b means of thrustscrews 17 insubstantialfy the same manner as adjustment of the biocks 11 iseffected. The blocks 11 and 15 are secured in desired longitudinaladjustment by means of suitable clampin bolts or screws.

The lower ap of the carrier A is supported upon drums or rollers 18,revolubly mounted in suitable bearings in the machine-frame. Saidrollers 18 operate to relieve said carrier from the strain due to itsown wei ht and cOntinuouSly the entire length thereof.

also prevent sagging of the carpet or other article when it passes ontothe lower lap of said carrier.

Supported above the upper lap of the carrier and, extending transverselyover the same are one or more airjets 19, adapted to project airdownwardly .uponthe carpet or other article supported upon said carrier,as

shown in Figs.,1 2, 2", 4, and 5.

My invention contemplates the use of any desired or approvedform ofair-jet. Iprefer, however, to use the form of jet shown in detail inFigs. 4 and 5 of the drawings, con prising' a" tubular chamber 20 and alateral chamber 21in open communication therewith,

by means of a justingsscrews 23, and any de-' sired width ofdischarge-opening may conveniently be provided by inserting washers 24of desired thickness-say one sixty-fourth of an inch:between the sidesof said dischargeopening; 1t isobvious that the width of the dischargeopening may be varied as desired byusing washers of differentthicknesses.

The air-jets 19 are preferably supported in such manner thatthedischarge-openings 22 will be directed downwardly upon the carrier at anacute angle,-rearwardly, and in such manner also that said air-jets willbe adjustable toward and from said carrier. In the preferableconstruction shown said air-jets 19 are provided with rectangular slides25, referabl formed integral with extensions t ereof, w -ch are fittedto and are freely movable in upri ht. uides or fiways formed instandards or raciets 26'; Supported upon the longitudinalframegrnembers. 1. Vertical adjustment of the air 'jet's 19 is effectedby means of screws threaded through the ends of the brackets orstandards 2,61 the, lower ends of which'areirevolubly' securgdagainstlongitudinal movementin the slides 25,-the relation being such that saidair-jetswillfbe properly directed. I f

Saidipe or jet 29 is provided with discharge ho es or openings on its upperside. Thus passing over the same the carpet will receive the full forceof the blast therefrom, thereby securing the greatest efficiency of op-The pipe orrjet 29 is designed for and when not desired for use may beturned pivotally so as to extend longitudinally of the machine at oneside of the carrier, as shown in Fi inwhich position it will notobstruct c. d, I 0 said carrier. Communication between the pipes or jets2S and 29 is controlled by. means of a valve '31 in the union 30.

As shown, air is supplied to the jets 19 and 28 through pipes 32, 33 and3,4, which communicate with a header 35, which is connected with asuitable source of supply of air under pressure. The pipes 32, 33, and34 are controlled by means of suitable valves, and the pipescommunicating with the jets 19 are connected thereto by means offlexible sections, thus providing for desired vertical adjustment ofsaid jets.

In order to render the operation of the blast from the air-jetsmoreefficient, means are provided for raising or loosening the pile ornap of the carpet beforeit reaches said jet. As shown, said meanscomprise brushes 36, revolubly mounted in suitable bearings in front ofthe air-jets 19. The brushes 36 are preferably adjustable toward andfrom the carrier A. To provide for such adjustment, the bearings forsaid brush are formed in guides 38, formed in brackets or standards 89,

ICC

boxes 37, fitted to and freely movable in bers 1. Ad ustment of saidbrushestoward and from the carrier is effected by means of screws 40,threaded through the ends of the brackets or standards 39, the lowerends of which are revolubly secured a ainst longitudinal movement in thebearin rboxes 37. R0- tation is imparted to the brushes 36 by means ofdrivingconnection with a suitable source of power. When the brushes 36are depressed so as to run incontact with the surface of a carpet orother article supported on the carrier, they will obviously operate toloosen and raise the pile or nap of said carpet, thus allowing the blastfrom the air-jets to penetrate said car et more easily and thoroughly,rendering the operation ofsaid jets much more efficient:

The carpet or other article to be cleaned maybe attached to the carrierin any desired manner. Preferably, however, the connec- [10 between saidcarpet and carrier will be elastic, thereby permitting the carpet toadjust itself to variations in the travel of the carrier, as in turningaround the end of the carrier from one lap to the other thereof, withoutsubjecting said carpet or other arti cle to any undue strain or tension.A desir able form of attaching device is that shown in Figs. (5 and T ofthe drawings, coniprising a clamp 42. adapted for attachment to the edgeof the carpet, and a clip 43, adapted for attacluuent to one of theslats 4 ol the carrier A, connected by means of a spring-link 44. Asshown, the'jaws of the clamp 4'. are adapted to he lirml set upon thecarpet by means of clamping-screws 45, and the clip 43 comprises ahinged member 46, adapted to'be secured in closed position around one ofthe carrier-slats 4 by means of a cotter 47. Any desired number offastening devices may be used necessary to properly connect said carpetto said carrier.

Preferably also, my machine comprises means for holding the carpet orother article llat upon the carrier A while being cleaned and forpreventing sagging of the carpet when it passes onto the lower lap ofsaid carrier. As shown, said means comprise cords 4 one end of each ofwhich is attached to the carrier A and the opposite end thereof to apositivelr-ilriven drum 49, the connection neing such that the surfaceof the drum 49 will move at the same rate as the carrier A, and thedriving connection being such that, as the points of attachment of saidcords to said carrier move awa from said drum the cords 45' will heunwound therefrom. and vice versa. shown in Fig. 1, the drum -19 isdriven from the front carrier-shaft by means of spur-gears i) ll.Preferably, also,thc cords in are attached to the carrier A by means ofspring-links 5t) which all'ord elastic connection between said cords andcarrier, thereby permitting said cords to adjust tl'iemsclves to slight\ttl'iutlons in the travel of said carrier, as when passing around theend thereof. 'ith the described construction it is obvious that as thecords 48 are drawn oil from the drum 4!) they will lie flat upon thecarrier A or upon the carpet or other article supported thereon andbeing at all times under considerable tension will operate to hold thecarpet llat and will also prevent sagging of the carpet on the umer lapof said carrier. As they prevent sagging of the carpet or other articleawav from the lower lap of the carrier when the carpet is carried aroundthe far end of the carrier, it is obvious that the drums or rollers inand the cords wiii suppiemciit each other.

'lhe carrier A. the cleaning instrumentalitics, and other operativeparts of the machine are inclosed in a casing 51. which is preferablymade ol' llt'tl metal swim-ed to a framework consisting of T-bars 52,supported upon the longitudinal frame members 1. The cusing 51 isprovided at its forward end with a hinged section or door 53, as shownin Figs. 1 and 2, through which carpets and the like may be drawn intoand removed from said casing in the operation of the machine. -At itsrear end it is contracted, so as to make a communication, preferably bya hollow cylinder 57", with an exhaust-fan 57, and beyond the fan andconnected with the chamber in which it revolves a connection 57",preferably tubular, is extended to a union with the discharge-pipe 54from the bottom of the casing, wl'iereby by the revolution of the fan adraft. is created, drawing the dust blown from the carpet or otherarticle and expelling the same through the extension-pipe leading fromthe fan into the discharge-pipe from the outlet-opening of the casing,wherein it is precipitated by the water flowing through saiddischarge-pipe and washed into the sewer or other drainage system. Thebottom of said casing is trough-shaped and declines from the front endtoward a discharge-opening 54 at the rear end thereof, so that wateradmitted to said casing will drain off through said opening.

Supported within the casing 51 below the carrier A is a pipe 55, whichcommunicates with a suitable source of waterrsupply. The supply of waterto said pi e 55 is controlled by means of a valve 56. he pipe 55 isprovided at short intervals with small holes or openings designed todischarge a fine spray into the casing 51, which will operate toprecipitate or wash down the dust and dirt expelled from the carpet andother articles by the airblast in cleaning the same intothe trough,whence it will escape through the discharge-opening 54.

An exhaust-fan 57, which communicates with the rear end of the casing51, operates to create a draft and expel dust and dirt from said casingnot removed by means of the spray.

To provide for disinfecting the carpet after cleaning the same, a tank58, designed to contain a suitable disinfecting solution, is connectedwith the header 35 by means of a pipe 59, controlled by a valve 60. Thecontents of said tank may be heated to any desired degree by asteam-coil 61 at the bottom thereof, which coil is perforated andconnected with a source of steam-Suppl by. a pipe 62, controlled by avalve 63. Io disinfect the carat, the supply of air is shut off from thelieader 35 and the valve opened, thus admitting steam impregnated withthe disinfectant from the tank 58 into the: header 35, whence it isdischarged into the casing 51 through one or more of the air-jets. Inpractice l pref er to admit the-disinfectant through the rearmo'st jet19 in order that the least possible amount of disinfectant may escapethrough the door 53 in the front end ol thicasing. After the carpet hasbeen exposed i to the action of the disinfectant a desired length oftime the valve on is closed, shutting off the supply from the tank 58;or it u'eferred, steam impregnated with the (hem ectam. may be, by themeans shown, in ected into the header 35 while the air-blast is on, thushcatiu" the air to any desired degree, and then t e same discharged soimpregnoted with the disinfectant u on the article to be cleaned anddisinfcctet as above dcscribcd, thus cleaning and disinfecting thecarpet or other material simultaneously w th the same blast. To avoidthe condensation of the steam impregnated with the disinfectant whendischar ed into the header, the an may of course be eated by anysuitable additional means, thereby increasing the ciliciency and forceof the compressed air; or instead of using an air-blastto carrv thedisinfectant in steam may be employed, as stated, into which may beintroduced directly the requisite amount of the disinfectant by themeans shown or any other suitable means, and whereby the car et or othermaterial ma be cleaned and disinfected at the same time and by the sameblast of steam im regnated with the disinfectant.

he carrier A is driven from any reversible source of power (not shown)by a belt applied to a pulley 64, secured to an extension of the frontcarrier-shaft.

The rocess of cleaning a carpet or other article y means of a machine ofmy invention is as follows: The 1))Qlt1i0l opens the door 53 at thefront end 0 the casing 51 and attaches an edge of the carpet or otherarticle t0 the carrier A, preferably by means of the clips described.The door 53 is closed and movement is then imparted to the carrier in adirection to draw the carpet or other article attached thereto into thecasing and beneath the brushes 36 and past the airjets 19 and 28,movement being simultaneously imparted to all other requisite andconnected cleaning instrumcntalities. hen the entire length of thecarpet or other article has assed the cleaning instrumentalitics in theorward movement of the carrier, the movement of the carrier is reversed,thus rcturning said carpet or other article to the door 53, throughwhich it will be removed.

It is obvious that the rearward movement of the carrier will expose thecar et or other article to the action of the c caning instrumentalitiesa second time. Ordinarily the two exposures of the carpet or the like tothe action of the cleaning instrumcntnlities will thoroughly cleanse it,but if it is very dirt v the process may berepeatcd as often as may bedeemed necessary.

Durim the o NTttilUll of the cleaning inst rnmcntalities the dust anddirt expelled from the carpet or the like thereby is either washed downby the spray- I from the pipe 55 or is drawn out ol the casing by theexhaust-inn 57, thus preventing an accumulation of dust and dirt withinthe cus ingfil. Al'tcr thccm'pct has been lhoroughl) cleaned the air isshut off from the jets, the exhaust-fan 57 is stopped, and steam i|n1.rcgnoted with disinfectant is admitted to the casing 51 from the tank 58in the manner heretofore dost :ibcd. 'lhis finishes the cleaning anddisinfecting and renovating operation, and the carpet or other articlemay he removed fl! on the machine.

With the apparatus described not only car cts and ro s, butllluttlbhSOS, blankets, am other simi ar articles or textile fabrics,may be readily and thoroughly cleansed, disinfected, and renovated witha minimum of labor and in an exceedinglv short time.

It will of course be understood that various changes may be made in thedetails of the construction shown without departure from the s irit ofthe invention.
